IMPROVEMENT l LANTERNS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that 1, T. B. BURGERT, ofCrestline, in the county of Crawford, and State of Ohio, have inventedcertain new and useful Improvements in Lanterns; and I do hereby declarethat the followingv is a full and lcomplete description of the same,reference being had to the accompanying drawings, making part of thisspecilication, in which- Figure 1 is a side view of the lantern.

Figure 2, a detached section.

Y Like letters of reference refer to like parts in the different views.

This invention consists in a new and peculiar manner of connecting orsecuring the top or cap of said lantern to the body of the same, wherebythe said cap can be removed with greater ease and facility than ifconnected to the body in the ordin'nry way.

This invention also relates to a peculiar device for adjusting the topor cap of the lantern to globes of different heights, hereinafter morefully described.

In g. l, A shows the bottom or lamp section of the lantern, to which theframe, or guard Bis attached, and whereby the rim O is supported, anunder-side view of which is shown in g. 2.

To said,rim is connected the top, or cap Il), as fol- In the edge ofsaid rim are cut two notches, a, g.

2. To the under side of the flange, or collar E, projecting from thebase of the cap, are secured a pairof lugs, or ear's, b, the relativeposition of which to the notches a, in the edge of the rim, referred to,is such that on adjustingthe cap, so as to bring said lugs to thenotches, as indicated by the dotted lines c, g. 1,

they will pass through them, thereby allowing the collar to flt downclose upon the rim, as shown in fig. 1.

Now, ou turning thelcap in the direction of the arrows, the lip e of thelug, or ear will be drawn under the edge of the rim, whereby it is heldfirmly thereto.

. In order toprevent the ears from escaping from their connection to therim, the cap is turned until the ear is caught by the spring f, in thehook of which the ear is retained, thereby preventing the cap from beingturned in either direction.

By this means the cap is not only closely secured to the rim, but isprevented from being detached by swinging about the lantern, while inthe act o'f carryin it or while giving signals.

he upper part of the l globe F is held in place by means of anadjustable removable cap, G, in the rim H of which the edge of the mouthof the globe ts,' and thereby held in proper relation to the top.

Said c'ap is maintained within the top by the resilient motion of thefrill h, fg. 2, also indicated by the dotted lines fi, fig. 1,surrounding the inside of the top as a lining. Said frill consists of aseries of metallic fingers, the base of which is secured to the side ofthe top, whereas the opposite ends are free.

1t will be obvious, that by this device lthe inward pressure of thefingers will clamp tightly the cap, which may be adjusted upward ordownward, as the .length or height of the globe shall make it necessary.Hence globes of unequal height can be used in this lantern, should it beexpedient in consequence of accident to a globe, rendering it necessaryto replace it with another of a slightly different height.

It will be observed that the bail I is not attached directly to the rim,nor to the top 'of the lantern, but is pivoted to the frame, or guard B,which is not the case with lanterns as`ordinarily made. In such the bailis connected directly to the top, the result of vwhich is, that onswinging the lantern, while carrying or signalling with it, the strainconsequent of such motion sometimes causes the top to become detachedfrom the body, breaking the lantern, and-endangering those having itinuse.

To avoidthis, the bail is attached to the frame at the points n, insteadof to the top. 'Hence there is no possibility of the top becomingdetached from the body of the lantern in consequence of swinging itabout for signalling, &c.

Another' objection to having the ears whereby the bail is connected tothe lantern attached to the top is, that the ears are usuallysolderedon, and, in consequenee of the heat, the solder softens, andscmetimesmelts, so that the bail comes o', which cannot happen when said bail isattached to the lantern in the manner as herein shown.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of the ears b, notches c, and spring f, with the topD, and rim O, when constructed to operate in the manner and for thepurpose substantially as described.

2. The spring frill h, and removable cap G, in combination with the topD, when constructed to` be applied and to operate in the mannersubstantially as described.
